My friend’s name is literally “Long”. I think that counts.

I’ve never met him but Mr Osas would have to be a contender

Native Hawaiian names can be pretty long.

Ken. I don’t get out much.

A girl I knew was called, and I shit you not: Estradivarius. 5 syllables. Yes, the same name as the clothing store which itself named after the string instrument.

Not the longest, but I once worked with a Thai lady named Soda Pop. She swore it was her real name, it was on all her work documents and everything.

My sister because she legally changed her name to include all her favorite names because she couldn’t decide on just 3. So all of them are 2-3 hyphenated names.

I work with a lot of folks in India with super long names and they generally have a shorter version everyone calls them by.

I think the longest for someone I’ve met is “Vishnuvardhan” but everyone calls him Vish.

Then the problem is having a dozen Vish’s.

No it isn’t.
